VALVE CON STBUCTION.

Application filed November 25, 1927. serial No. 235,588.

ma be removed when it becomes necessary tov rep ace the same because ofdefects, or where the bladder has become ruptured as deslred to save the valve.

Another object resides'in providin such a valve structure, which may be me ly and eflicientl clamped in position wit respect to inflated ladder.

will become apparent as the same is better understood from the specification and claim to follow.

In the drawing Figure 1 discloses a fragmentary view of a conventional bladder, showing my improved.

valve construction in sectional detail view, and h Fig. 2 discloses a top plan view of the improved valve structure.

Nowior a more detail description ofmv inventioml refer to the drawings, in who like numerals designate like parts. In the drawingffor the purpose of illustrating the manner in which my im roved valve construction is associated wit the flange 2 and the'cup 1, theniaterial is thickened at 3, for the obvious'purpose of strengthening thesame. h

inflatable bodies, I designate a conventional bladder A, of a football, basketbalhxor the like. The bladder is As is shown in the drawing, the diameter of ,this cap is substantially the same as the diameter of the opening formed in the inflatable body A. A tapering tubular member 4 is adapted for disposition within the cap and is .greferably polygonal in cross section, wherey an insertable wrench may engage within the same, for removing the same from its complementary relation with the cup 1. The inner end of the tubular member is provided with a relatively thick wall 5, having a threaded bore substantially, through the cells ter thereof. The outer open end of the tube r is formed with the laterally dis 'osed circumf ferential flange -6, its under si e adapted to engage the portion of the inflatable member adjacent the opening therein, .while its top surface is converged toward the bladder.

As is clearly shown in Fig. 1 of the drawing, a valve body B of conventional tp e,--

- especially the type having its longitu' inal Other very novel objects and advantages extent threaded in a manner as shown. The inner end of this valve body is adapted to be secured by welding, soldering, or any other well known process, within an opening in the inner wall of the cup 1. This valve body is adapted to project u wardly through the cup and to terminate substantially flush with its top'edge.

When the bladder is in deflated condition,

the cup 1 may easily be inserted through the inwardly to the poin't where tlieflange B is engaging the washer 7 tightly against the bladder, the flange 2 is in a clam ing position against the inner side of the bla der.

In this manner, it will be seen that this structure provides a novel and efficient valve construction, wherein the liability of leak is reduced. It will also be seen that I have provided a valve device, which while perhaps costing slightly more in cost to. manufacture,

the same may be retained after a bladder has been ruptured, and is employed in conjunction with a new bladder. Having thus described my invention, what 5 I claim as new is In a valve securing means for inflatable bladders wherein it employs a conventional threaded valve body, a cup having a flange at its open end adapted to bear against the inner 10 side of theplate about the usual valve receiving opening therein, said cup adapted to have the conventional threaded valve body extending therethru, a tube having a flange at its outer end engage'able with the outer side of the bladder, the inner end of the tube being in threaded relation with the threaded valve body, whereby the flanges may be clamped to opposite sides of the bladder.

In testimony whereof I afiix my signature.

JOHN L.-FITZPATRICK.
